Brad Arnold, the lead singer of American rock band 3 Doors Down, has announced that he has been diagnosed with stage 4 clear cell renal carcinoma, a type of kidney cancer that has metastasized to his lungs.

The diagnosis came after he experienced illness and sought medical evaluation.

In an emotional Instagram video shared on May 7, 2025, Arnold, 46, revealed his diagnosis to fans, stating, “I’ve got some not-so-good news for you today.”

Despite the severity of his condition, Arnold expressed a positive outlook, citing his strong faith and lack of fear.

As a result of the diagnosis, 3 Doors Down has canceled their 2025 summer tour, which was scheduled to begin in Daytona Beach, Florida, on May 15. All tour dates have been removed from their official website and replaced with a direct message from Arnold to fans.

Arnold referenced the band’s 2008 hit “It’s Not My Time” in his announcement, suggesting a personal connection to the song amid his health battle.

The band, originally formed in 1996 in Escatawpa, Mississippi, became widely popular with their 2000 single “Kryptonite.” Arnold is the sole remaining founding member of 3 Doors Down, as other original members have departed the band due to legal issues and health problems.

Fans and fellow musicians have expressed their support for Arnold, with messages of strength and well-wishes flooding social media platforms.

Despite the challenges ahead, Arnold remains hopeful and determined to face the battle with faith and the support of his fans.
